摘　　要：针对服务区域水质情况和出水水质要求,东莞市某污水处理厂扩建工程选取了改良多级AO系统作为主要生化工艺,并考察了其运行效果。结果表明,在污泥龄25.1 d、总停留时间18 h的工程条件下,本系统的改良多级AO系统能够高效脱氮除磷,保证主要污染物稳定去除,其中COD、BOD5、NH_(3)-N和TP平均去除率分别达到了92.04%、93.75%、97.56%、92.74%,出水均能稳定达标排放。本研究可以为实际生活中低C/N比的生活污水处理提供参考。According to the water quality of the service area and the effluent quality requirements,the improved multi-stage AO system was selected as the main biochemical process in the expansion project of a sewage treatment plant in Dongguan,and its operation effect was investigated.The results show that under the engineering conditions of sludge age of 25.1 d and total residence time of 18 h,the improved multi-stage AO system can efficiently remove nitrogen and phosphorus and ensure the stable removal of main pollutants.The average removal rates of COD,BOD5,NH_(3)-N and TP reach 92.04%,93.75%,97.56%and 92.74%,respectively.The effluent can be stably discharged to the standard.This study can provide a reference for the treatment of domestic sewage with a low C/N ratio.
